Marathon American Spirit Oil

[chilson450]

I bought some of this oil today in 10w30. I cant find much information on it. I can get it for less than 2.00 a quart. I have read online that it is made by pinnacle oil. It has the API symbol and is SN/GF5 rated. It would be mainly going in GM 5.3 and 6.0 engines. Does it look like a decent oil or should I stick with the name brands? I guess Im worried that because it is a less expensive oil it will be lacking something or not work as well. Here is a link to the 5w30 version of it.

from your link, the dino version meets all the requirements, I would be content using the synthetic version.

In northern Michigan I would be using a name brand synthetic 5w30 for easier year round starting. The Oil appears to be fine but are you content with just good enough?

I've thought about trying it sometime, but at gas station prices I'm better off just getting MaxLife or white bottle Valvoline from Wal-Mart.

On paper it's very similar to this other Pinnacle oil available at Menard's for $2.24 / qt. (and sometimes goes on sale for $1.79 / qt.)

I've used the 5W-20 National (Pinnacle) twice in the warmer 6 months of the year here up to 5K miles O/FCI with no issues. I bought 3 jugs back when they had it in 5 qt. jugs on sale.

Marathon is a big enough company involved in both oil and petroleum that I doubt they'd put their branding on an inferior product.

I'd run it at 5k intervals and sleep well at night. $2/qt is a heck of a deal.

For $2 a quart i would get the Formula Shell oil at Home Depot.
